The metal welds without a factor which is of extreme porosity or cracking, molten copper will seep importance, because through cracks or pores and attack the iron base.

The alloy, as thus described, may also be used in the form of castings, in cases where the castings are used outside of the copper converter and are not in contact with white metal, which is C1125.

\ about 4 copper in amounts of from about .5% to about 3%, and carbon from .5% to 1.75%, the balance consistin essentially of iron.
